SPECIFICATION formingpart of Letters Patent No. 595,566, dated December14, 1897.

Application filed December 14,1896. Serial No. 615,668. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH R. GUMP, a citizen of the United States,residing at Milan, in the county of, Washtenaw and State of Michigan',have invented certain new and useful Im-, provements in Checkrein-Hooks,of which the following is a specification, reference being had thereintothe accompanying drawings.

The invention consists in the construction of a checkrein-hook designedto facilitate the disengagement of the checkrein after being vation ofmyimproved hook,showing it closed.

Figs. 2 and 3 are similar views showing it fully and partially open.

A is the base, having suitable securing means, such as the stub-bolt B,and provided at the top with a U -shaped hook C. The forward arm a ofthis hook is made with a groove 1), which is formed between the sideflanges c, the side flanges merging into the base. The rear arm 01 isbifurcated, or is formed simply by the extension of the flanges alone.In the bifurcation of the rear arm is a substantially C-shapedlocking-frame D, pivoted on the transverse pin E, and having projectingfrom near its pivotal point'the actuating arm or lever F. Thislocking-frame has a checkingarm G, which lies between the bifurcationsof the arm (1, and its outer end fits in the groove in the forward arm.The upper arm H of this frameis adapted to bridge the space between thetops of the two arms (1 a.

In the upper end of the arm a and lying within the groove in that arm isa spring-catch I, provided at its upper end with a bend or shoulder J. VThe arm H is provided with a locking-tongue J, which is provided with acorresponding recess in which the shoulder of the spring-catch isadapted to engage to hold the parts in the closed position shown in Fig.1.

The arm G is of such a length and so arranged that in its openingmovement it will bear against the spring-catch, cleaning out any dirt ordust that may have accumulated therein in use, and as its end reachesthe shoulder on the spring it is forced above the same, as shown in Fig.2, in which position the spring maintains the hook in its open position,so that the operator can more readily remove the checkrein without theinterference of the hook.

By using the spring-catch I and arranging it so that it conforms to theinner face of the hook within the groove I obtain a long easy workingspring which permits me to engage anddisengage the locking-frame withlittle effort and without danger of its breaking with any ordinary use,the spring being protected by being locked in the groove and kept cleanand free from dust by the action of the arm G.

What I claim as my invention is- In a checkrein-hook, the combinationwith a base and securing means, of a substantially U-shaped framethereon, a shouldered locking-spring at or near one end of the frame,and a substantially C-shaped hook pivotally secured to the oppositebranch of the frame, one end having a locking-shoulder thereon arrangedto engage the shoulder of the spring and the opposite end being formedof a length sufficient to carry its end outward to a point to engage thesaid spring-shoulder and rest thereagainst when the hook is in its openposition, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH R. GUMP.
